“I never use Wi-Fi networks, so man in the middle attacks via Wi-Fi are not my problem” told us an executive of a large organization during a demonstration of the Skycure’s innovative mobile security solution.
- The attacker needs to be physically close to the victim
- The victim needs to first connect to the rogue Wi-Fi network
iOS devices hold predefined mobile carrier settings under /System/Library/Carrier Bundles. We examined this directory and discovered many bundles that actually contain definition of Wi-Fi settings. Below is a sample list of carriers and the associated SSID(s) of networks they pre-configure on the device. While some of bundles include SSID passwords in plain text, we have decided not to publish them.
|SKT_kr||T wifi home||Softbank_jp||mobilepoint|
|SFR_fr||SFR WiFi Mobile||SKT_kr||T wifi zone_secure|
|SingTel_sg||SingTel Highspeed WIFI||Sonera_fi||homerun1x|
Putting the attack to test
We wanted to put the attack to a test without actually attacking anyone or compromising their privacy. We decided to create several Wi-Fi hotspots and simply count the number of devices that got connect to them. In order to do so, we used a simple D-Link router, installed dd-wrt firmware on it, and created several virtual Wi-Fi interfaces. We’ve set the SSIDs according to the networks listed in the carrier bundles list, as well as based on common Wi-Fi SSIDs. We are going to perform a first live demonstration in the Third International Cyber Security Conference, and will be sure to report back on our results.
Is this threat being exploited?
